IMPROVEMENT IN HAND-STAM PS.

Specification forming part of Letters Patent No. 204,421, dated June 4, 1878; application filed May 1o, 187e.

To all whom it may concern:

Beit known that I, EDMUND D. CHAMBER- LAIN, of Westfield, Union county, State of New Jersey, have invented a new and Improved Stamp, which can be attached to an ordinary lead-pencil; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in whichj Figure l is a perspective view, showing the stamp attached to the pencil. Fig. 2 is a longitudinal section. Figs. 3 and et are details to be referred to. l

The object of my invention is to provide a convenient printing-stamp to attach to a leadpencil; and it consists in a casing having on its upper side two griping-blades for holding the pencil, an inking-pad within it, a rotating die turning within the case on journals moving in slots in the ends of the case, and held down in the lower point of the slot and out of contact with the inking-pad by means of a spring lying along the top of the said casing, and connected with two depressing-plates lyin g against the ends of the casing, and provided with semicircular sockets, in which sit the journals of the rot-ating die.

In orderl'that those skilled in the art may make and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A is a rectangular casing, having projecting from its top two spurs or blades, a a', between which a pencil, B, can be forced to make a handle after two short grooves are cut in the wood of the pencil. Along the top of the casing and surrounding a a is a dat spring, C, held down by means of burrs b b, struck out of the casing or otherwise. The ends of spring C are attached to two vertical sliding plates, D, provided with semicircular recesses d, to rest over the journals of a rotating die, E, journaled in slots c in the ends of the casing, and provided with a projecting handle, f, by which to turn it. Inside the casing, and next to its top, is an inking-pad, P.

The casing is made from a struck blank, as seen in Fig. 4, the sides and ends being bent down at the points shown in dotted lines, and not further secured. This construction allows the turning of the die, which springs out the sides in turning, and the sides retract and hold the rotary die when its sides are in a proper plane for printing. The spring C, through the medium of the plates D, presses the journals of the die to the lowest point of the slots e e, and keeps it away from the inking-pad P.

When it is desired to ink the die E it is only necessary to press the thumb on the reverse of the plate, when the spring C gives, and lets the die pass into the case until it comes in contact with the pad. 0n removing the thumb the die moves to the bottom of the slots, which is a sufficient distance to allow the die to be turned without touching the ink-pad in its halfrevolution.

It is evident that the end pieces D can be made integral with the spring without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The stamp-case A, provided with projecting gripin g blades or spurs a, a. for holding the pencil, substantially as set forth.

2. The casingA, provided with an inkingpad, P, in its upper inside surface, and end slots e e, in combination with the rotating die E and spring C, constructed as described, whereby the die is normally held away from contact with the inking-pad, substantially as and for the purpose set forth.

EDMUND D. CHAMBERLAIN.
